如何在Firebase上保存数据? [英] How to save data on Firebase?

问题描述

我参加了一个教程，以在React Native中在Firebase上保存日期.

I take a tutorial to save date on Firebase in React Native.

当我编译时显示错误为_firebase2.default.database.ref is not a function

When i compile it that show the error is _firebase2.default.database.ref is not a function

但是官方教程也是.ref的问题. https://firebase.google.com/docs/database/web/读写

But the question that offcial tutorial is .ref too. https://firebase.google.com/docs/database/web/read-and-write

任何人都可以教我如何解决该问题，谢谢.

Any one can teach me how to solve the issue , thanks in advance.

我在Firebase上的规则设置:

My rules setting on Firebase:

{
  "rules": {
    "users": {
      "$uid": {
        ".read": "$uid === auth.uid",
          ".write": "$uid === auth.uid"
      }
    }
  }
}

在React Native中保存数据代码:

Save data code in React Native:

export const employeeCreate = ({ name, phone, shift }) => {

    const { currentUser } = firebase.auth();

    firebase.database.ref(`/users/${currentUser.uid}/employees`)
    .push({ name, phone, shift });

};

推荐答案

您使用错了.

当您直接引用Firebase时，您应该像这样使用它

When u directly reference firebase, you should use it like this

firebase().database().ref('---whatever---')
